Abstract
A power transmission joint comprises a pair of rotational members each having a rotation axis and arranged so as to be axially spaced from each other. A guide pin is disposed between the pair of rotational members and has an end portion thereof rotatably and swingably engaged with opposite end portions of the rotational members at rotation axes, respectively. A pair of drive pins are arranged symmetrically with respect to and in parallel to an axis of the guide pin and each is engaged with the opposite ends of the rotational members so as to transmit torque while allowing the drive pins to slide in a radial direction on the rotational members, swing and axially slide. A member is disposed between the pair of rotational members and rigidly ties the guide pin and the drive pins to keep a prescribed fixed relation therebetween.
